have multiple Verification channels

We need to have multiple Verification channels; as the stable is on almost all devices, Preview is for up coming & the only one we can change and test the firmware or holding back devices in is the Verification Channel

but as the customer has more than one case opened for a several affected devices, and each device needs a deferent versions testing, that will occupy the Verification channel and make it difficult to do testing with different firmwares on one device.
